The oxidation reaction occurs when the carbon material including the CFC is in the following temperature environment:

About 370℃ in the air

At 650℃ in water steam

About 750℃ in the CO2

The oxidation rate will increase rapidly with increasing temperature after exceeding 500℃.

Oxidation can lead to a substantial decrease in the mechanical properties of the CFC.

In general, 1% of oxidized weight will reduce the strength of CFC by about 10%.

Oxidation loss of 10% would result in a nearly 50% decrease in the strength of the CFC.

Therefore, the application of CFC as high-temperature materials in the aerobic environment will be greatly limited.
